Short Description: Aggregated Account Item multiple-Account context submenus
Bug Number: n/a
Release notes (y/n): no
For Release Nums: 6.1

Implemented dynamic multiple-Account context menus for Aggregated Account 
Items.  The two-level context menu for an Aggregated Account Menu is this:

  //=====================================================================
  //  Edit Account >>  (one item for each Account)
  //  Open Account >>  (one item for each Account)
  //  -------------------
  //  Display Group Membership >>  (list of display groups for the item)
  //=====================================================================

------------------
AccountGfxItem.hpp
AccountGfxItem.cpp
------------------

Make the "smarter" Account name tooltip text available to also the dynamic
Aggregated Account Item context menus.  This includes the Account's parent
Aggregegate Object Element Object name, like this: "element^account".

   static QString acctToolTip (const Account*);

(This is an enhancement of the original Qt3 Accounting View implementation).

------------------
AcctRowGfxItem.cpp
------------------

When "redirecting" a context menu account for an Account Item, pass the
Account Item of SimObjGfxItem::showAcctContextMenu().

-----------------
SimObjGfxItem.hpp
SimObjGfxItem.cpp

Implementation of dynamic multiple-Account context submenus for showing
the "Edit Account" and "Open Account" dialogs:

  void showAcctContextMenu (AccountGfxItem*, const QPoint& screenPos);
  void editSelectAcctTriggered();
  void openSelectAcctTriggered();

In the dynamically built submenus, the index of the Account within the
WorkspaceGfxScene's AccountGfxItem* _objSceneCtxAcctItem which corresponds
to each submenu item's Account is encoded in the QVariant "data" of the
item (a QAction).

WorkspaceGfxScene.hpp
WorkspaceGfxScene.cpp

New support for Account Graphics Item context menu, which now can refer
to more than one Account (in case of Account Item aggregation):

  // Context-Operation Account
  AccountGfxItem* _objSceneCtxAcctItem;
  AccountGfxItem* getObjSceneCtxAcctItem() const 
     { return (_objSceneCtxAcctItem); }
  void setObjSceneCtxAcctItem (AccountGfxItem*);
